Overview
The Central Semiconductor Corp 1N5297 BK TIN/LEAD is a silicon current regulator diode housed in a DO-7 glass axial leaded package. It provides a stable regulated current of 1 mA with a maximum limiting voltage of 1.35 V. The device operates within a temperature range from -65 °C to +150 °C and features a maximum power dissipation of 0.5 W. Designed for through-hole mounting, this single-element component utilizes a hermetic glass seal to ensure reliability in demanding electronic circuits requiring constant current sources.
Feature Summary
- Maintains a constant output current regardless of input voltage variations within operating limits
- Utilizes a robust glass axial leaded construction for environmental protection
- Operates reliably across an extended industrial temperature spectrum
Applications
- Constant current sources for LED driving applications
- Biasing elements for transistor amplifier stages
- Current limiting protection in sensitive circuit loops
Procurement Notes
Verify the specific ordering suffix against manufacturer documentation to confirm pinout orientation and terminal plating specifications. Ensure the selected variant matches the required thermal management capabilities for the intended enclosure design. Cross-reference datasheet parameters with system requirements before finalizing procurement orders.
Selection Notes
Select this component when a fixed 1 mA regulation is required without complex feedback networks. Verify that the series resistance allows sufficient voltage headroom above the 1.35 V limit. Consider the DO-7 package dimensions for PCB layout constraints and thermal dissipation needs relative to ambient conditions.
Part Context
This part belongs to the standard current regulator diode family produced by Central Semiconductor. It serves as a passive alternative to active current sources, offering simplicity in circuit design. The DO-7 package is a legacy form factor commonly used in through-hole designs where space is less constrained than in surface-mount applications.
Replacement Considerations
Equivalent parts include JANTX1N5297UR and other variants from manufacturers like Microsemi or Cobham. Verify that substitute components maintain the same 1 mA regulation and 1.35 V limit. Check package compatibility and thermal ratings before implementing any cross-brand replacements.
